Abstract
PURPOSE: To shorten the transmission time in the case of the code transmission and to increase the S/N in the case of the analog transmission respectively by selecting either one of the two color information in preference for transmission when the color information of two or more colors are detected simultaneously form the original surface.
CONSTITUTION: The picture of original 1 is condensed through lens 2 and then divided into three parts through half-mirrors 3a and 3b. The light transmitted through mirror 3a enters photoelectric converter 5a, and the reflected light enters mirror 3b to be reflected to photoelectric converter 5b via filter 4a. And the light transmitted enters photoelectric converter 5c via filter 4b. Converters 5a∼5c deliver the signals of the high and low potential when the volume of the incident rays is large and small respectively. Outputs a∼c are supplied to level deciding circuits 6a∼6c to deliver the signals of the logic level. Level comparator circuit 7 compares output b with c to deliver the logic level signals of 1 and 0 when b is lower and higher than c respectively. The outputs of circuits 6a∼6c plus circuit 7 are supplied to logic circuit 8 to generate the selection output.
